You're probably right.
I've played around with LISP macros a little, but it seems that most
of the cases where you would use a macro in LISP you don't need one in
haskell due to lazy evaluation. Although I haven't played around with
them enough to say much one way or another.
Do you know of a particular example where a macro would be a big help
